UFC on Xbox Live: Full-access octagon

At least, that's the impression I get after spending about half an hour with the upcoming UFC app for Xbox Live. It does a lot of cool things in its capacity as Xbox Live's first true Pay-Per-View offering -- more than any Pay-Per-View implementation I've ever seen. But the ability for Xbox Live members to interact with their friends list, to effectively compete against each other for the most accurate fight picks, might be the thing that sticks out the most. And it makes Vegas jealous to boot.
